Oil Dielectric Breakdown Voltage Tester - Overview

The PORTATEST A-2 Oil tester is a fully automatic tester for the determination of the dielectric breakdown voltage of the insulating liquid. Otherwise known as a flashpoint tester. It has been designed for laboratory use as well as field use for servicing and commissioning. The PORTATEST A-2 is very comfortable and easy to use. The requested testing standard may be selected via the menu. The corresponding electrode type as well as the electrode spacing will be displayed for confirmation before starting the test. After placing the test vessel with the oil sample into the test chamber, the protection lid needs to be closed. For maximum operator security, the protection lid is equipped with a security interlock key switching off the HV when opened during testing. When starting the test, sample temperature as well as a customer-specific sample number may be entered and will then be integrated into the test report printout. The testing sequence according to the selected testing standard is performed fully automatically.
